“Many men are looking for safe, effective ways to improve their sexual performance and satisfaction. The P-Long Protocol offers a proven, non-surgical solution backed by peer-reviewed clinical research.”
Whether it’s concerns about size, sensation, or erectile function, the search for solutions is common — and now there’s a proven, non-surgical option: the P-Long® Protocol.
Developed by board-certified urologist Dr. Judson Brandeis, the P-Long Protocol uses your body’s own healing power to promote natural growth in both length and girth. This method combines Platelet-Rich Plasma (PRP) injections with supportive devices and supplements to deliver real, lasting results — without surgery or fillers.
What Is the P-Long Protocol?
At the heart of the P-Long Protocol is a modified P-Shot®, which involves injecting PRP (taken from your own blood) into specific areas of the penis. PRP is rich in natural growth factors that stimulate new tissue growth and increase blood flow — two key elements for size gains and better erections.
To enhance these effects, the treatment also includes a carefully designed at-home regimen combining four coordinated components:
When Will You See Results?
Setting the right expectations is one of the biggest predictors of success. Here’s what happens month-by-month.
The most common reason men don’t see optimal results isn’t the protocol — it’s quitting during the early cellular regeneration phase when nothing looks like it’s happening. Stay the course.
The Patient Experience
Is It Painful?
The treatment involves two injections into the shaft of the penis. Numbing cream is used to reduce discomfort, and optional Pronox (nitrous oxide) can be added to make the experience even easier. Most patients report only mild discomfort.
Is There Downtime?
Minimal. There may be minor swelling or bruising after PRP injections, but most patients return to normal activities the same day.
Does It Really Work?
In the published Brandeis et al. 2023 clinical study (which you can view here), every participant had positive results — averaging about an inch in length and half an inch in girth over 6 months. Some men saw even greater gains.
At Prestige Medical Group, our patients have had excellent results and are happy with their treatments. See real before & after photos.
P-Long + ED Enhancement
While the primary goal of P-Long is size enhancement, 100% of participants in the published study reported improved erectile function. At Prestige Medical Group, we routinely treat men with erectile dysfunction using a customized P-Long approach.
Based on your SHIM score at consultation, Dr. Gabal may recommend adding complementary treatments:
- ShockWave Therapy — often added for mild ED to improve blood flow
- Apex RF — radiofrequency treatment for enhanced tissue quality
- Exosome Therapy — advanced regenerative option for select candidates
- Priapus Toxin (Bocox) — botulinum toxin therapy for ED support
The right combination is determined case-by-case at your consultation.
Important: No Tobacco or Marijuana Use Allowed
Tobacco use — including smoking, vaping, or chewing — can severely reduce the effectiveness of this treatment. Nicotine narrows blood vessels, limits blood flow, and weakens your PRP quality, making growth and healing less likely.
Marijuana increases the risk of erectile dysfunction and can compromise results.
For best results, you must be nicotine and marijuana-free before starting the P-Long Protocol.
